10.3 Rio still includes a Free IntraWeb Bundled Edition.
The English ISO (and likely other languages) have IntraWeb included, however the Community Editions, and some non English distributions do not include it or have it deselected by default.
Whether it is included or not, you can still get IntraWeb 14 for free in your version.
From Embarcadero’s own website:
The version that Embarcadero includes is over 10 years old. We offer a FREE update which includes over a decade of new features and bug fixes.
Upgrade to IntraWeb 15 (and 17!)
A purchase will also provide IntraWeb 17 to you when released in early 2019. IntraWeb 17 is a massive step forward and includes WordPress support, JQuery UI, ChartJS, FullCalender IO, ExtJS, Boostrap and much more.
